Several of the intercommunicator collective operations contain statements along the lines of "Both groups should provide the same count value".  However, what is really required is that the (count,datatype) tuples describe the same type signature.  See MPI_Allreduce and MPI_Reduce_scatter.  I propose a clarification that replaces the text that refers only to count to "Both groups should provide count and datatype arguments that specify the same type signature."
